Thymosin Alpha-1 vs Epitalon
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
Thymosin Alpha-1
Thymosin Alpha-1 is a peptide naturally produced by the thymus gland that plays a crucial role in immune system modulation. It is approved in over 35 countries for various conditions including hepatitis B and C.

| Aspect | Thymosin Alpha-1 | Epitalon |
|---|---|---|
| Mechanism | Enhances T-cell function and maturation, stimulates dendritic cell activity, and modulates cytokine production. Promotes the differentiation of stem cells into mature T lymphocytes. | Stimulates telomerase production, which can lengthen telomeres on DNA strands. May also regulate melatonin production and circadian rhythms. |
| Typical Dosage | Clinical dosing typically ranges from 1.6mg to 6.4mg administered subcutaneously 2-3 times weekly. Research protocols may vary. | Typical protocols: 5-10mg daily for 10-20 days, repeated 2-3 times per year. |
| Administration | Subcutaneous injection. Often used in cycles or as part of comprehensive immune support protocols. | Subcutaneous or intramuscular injection. Usually administered in cycles rather than continuously. |
| Side Effects | Generally well-tolerated. Rare side effects include injection site reactions, mild flu-like symptoms, and temporary fatigue. | Generally well-tolerated. May affect sleep patterns initially. |
